Abstract (en)

[origin: EP1691545A2] A scanning line interpolating apparatus has a scanning line interpolating unit (101) for converting an inputted interlaced scanning picture to a progressive scanning picture by using motion compensation, a motion vector search device (102) that searches for a motion vector for use in the motion compensation, and a control unit (104) for controlling the precision with which the motion vector is searched for. The control unit (104) is adapted to determine the search precision on the basis of a pixel structure of a display device (105) for displaying the progressive scanning picture.
